The new 1200 Classic features a completely redesigned base and drive system which was developed after years of studying and evaluating tumbler performance. The 1200 drive system has a beefed up suspension system and built in “exciters” for better tumbling action and faster case cleaning. The new drive system has improved air flow for cooling and guaranteed longer motor life. Combined with our new Anti-Rotation Pad Mounts the 1200 Classic runs smoother, quieter and better than ever before. Capacity of 350 .38 Special cases. For reloaders seeking the ultimate in case cleaning convenience, only Lyman offers the patented “Auto-Flo” system. Auto-Flo models automatically separate clean cases from media by using the units normal vibrating motion. When cases are clean, the user simply pulls the drain plug and the media drains from the exit port into the media drain pan (included).
